4326超长综放面矿压显现规律分析

Analysis on Coal Pressure Appearance Rule in 4326 Superlong Fully-Mechanized Mining Workface

以现场矿压观测资料为基础 ,结合矿山压力理论对国内第一个超长综放面来压规律及特点进行简单分析 ,初步掌握了超长综放面的来压规律 ;并从来压步距、强度、支架压力及运行状况等方面与普通综放面进行对比分析 ,得出超长综放面有别于普通综放面的来压特征 ,可为今后设计、布置和回采类似工作面提供科学依据。

This paper analyzes pressure rules and features of first superlong fully-mechanized mining workface in our country through coal pressure material in scene and coal pressure theory,knowing well pressure rules of superlong fully mechanized workface with the beginning.It compares common fully mechanized workface with superlong fully mechanized workface in distance,strength,shield pressure and motion.Differentiating one from the other in features.This paper is a scientific basis for reference with design,arrangement and mining this workface.
